A Home Office advisory committee has ditched research assessing the impact of international students after academics labelled it "unethical".
The survey, set up by the Migration Advisory Committee (Mac), which informs Home Office policy, asked for students' views on international classmates.
But it could be completed by anyone and some said it posed "loaded" questions.
A Mac spokesman stressed the survey was "not designed to be discriminatory", but confirmed it was being withdrawn.
"Following online commentary it has become apparent to us that we will be unable to use the responses to the survey," the spokesman said.
The committee defended the survey, saying it was "simply an attempt to ask students for their experiences" and "had the potential to show a very positive view of international students in the UK".
However, on Thursday, it concluded the survey "cannot now be used to add to our evidence base".
